STILL.

applicati@ filed August `5, 191e. serial NQ. 315,503.

To all whom t may concern.'

Be itl known that I, HENRY C; P. WEBER,

a citizen of the United States, and a residentv of Edgewood Park, in the county of Allegheny and State of Pennsylvania., have invented a new and useful V,Improvement in Stills, of which the following is a specification. f My invention relates to stills, and more particularly to stills for use in chemical laboratories, and it has, for its primary obj ject, the provision of an apparatus of the above specied character which may be conveniently'manipulated and which shall be etcient in use, particularly in connection with vacuum distillation.

, My still is primarily intended for use in fractional-distillation operations and, for this reason, another object of my invention resides in constructing a still provided with a plurality of liquid containers so kdisposed and communicating'in such manner that the liquid may be initially introduced into one container and various fractions thereof may be distilled olf from various other containers by properly diso posing the still and by subjecting the various I containers to baths of suitable cooling fluids,

if desired.

Another object which I have in view is to construct a still in such manner that the contents of any container may be poured from the still independently of the contents of the other containers and so that the contents of any container may be `poured into any other selected container.

With these and other objects in view, my invention will be more fully described, illustrated in the drawings, in the several views of which corresponding numerals indicate like parts, and thenparticularly pointed out in the claims. j

In the drawings, Fig. l is a plan view of my still, and Fig. 2 is a side elevation thereof.

My still preferably comprises two co` relative still-units l and 2, which may be employed separately but which are preferably and, in most instances, joined to proi0 vide a compound-still structure. 'The units may be identical in construction and are substantially se shown in the drawings.

Each unit or section may comprise a pair of glass flasks 3 and 4, having elongated 5 necks 5 and, respectively, which are disbent,

' be joined to the neck this container to the the other units.

posed at an angle of substantially to' each other, but so that no common plane may be passed throughboth of them,` the end yof the latter neck being fused into the intermediate portion of the former neck to communicate therewith. The end portion of the neck 6 may be slightly reduced and be or curved, at an angle yof from to 90O to the remaining portion, as desired, and 5 at an angle of 60 to 900, being inclined,fif at all, in the direction ofthe flash 3..

A relatively small` tube 7 communicates with the curved portion of the neck 6 of each unit, extending outwardly and radially therefrom and having its free end bent to extend away from, 'andsubstantially at right angles to, the neck l j the two units are to beemployedas a cornpound still, a stopper 8, or equivalent means, may be utilized'to detachably connect the, free end of the branch tube 7 of one unit with the open end of the unit.

It will be obvious that the manner of connecting the units `is such that either unit may be turned withrespect to the other so that the flasks orcontainers of one unit may be disposed in various relative positions, not only with respect to each other but also with respect to the flasks or containers of Because of this, it is possible to distill fractions of a liquid contained in one iiask to various selected flasks by successive adjustments of the parts without necessitating any pouring of the liquid from one flask to another.

Furthermore, this relative adjustability of the units permits, if desired, pouring of the liquid from many-lasks to any selected flask.

Although I have illustrated my invention as comprising two connected and cooperating` units, it will be appreciated `that either unit may be separately employed and will function as a complete still for certain purposes. Furthermore, additionalV units of like character may be added, if required, for more complex distillations. For these reasons, and also because the necks of the liasks and the branch tubes leading therefrom may be disposed at somewhat' different angles than those illustrated and described, it will be appreciated that no limitations are to be imposed upon my invention other than those set forth in the appended claims.

of the same unit, In use, when neck 5. of the other y other, and a branch I claim as my invention 1. A still comprising a pair of flasks having the neck of one communicating with that of the other and integral therewith.

v 2. A still comprising a pair of flasks having the end of the neck of one communicating with an intermediate portion of the neck of the other and at an angle thereto.

3. A still comprising a pair of flasks having their necks disposed at an acute angle to each other and the neck of one communieating with that of the other.

4.' A still comprising a pair of flasks having their necks disposed at an acute angle to each other, the free end of the neck of one being bent and communicating with an intermediate portion of the neck of the tube leading from the bent portion of the said neck.

A still comprising a plurality of units each including a. pair of flasks having the neck of one communicating with an intermediate portion of the neck of the other, and a communicative connection between the unitsL 6. A still comprising a plurality of units each including a pair of flasks having the neck of one communicating with an intermediate portion of the neck of the other, and a communicative connection between the units,'the connection permitting adjustment of the units relatively to each other.

7. A still comprising a pair of flasks hav- Aing the neck portion of one flask bent and communicating With an intermediate portion of the neck of the other ask, a branch tube leading from the curved portion of the first neck, a second unit corresponding to the first, and means for detachably connecting the branch tube of one unit with the unbent neck of the other unit.

8. A still comprising a plurality of flasks,

the neck of each flask having communication with the neck of another flask, and an adjustable connection between certain of the flasks.

9. A still comprising a plurality of flasks having inter-communicating necks, additional flasks having inter-communicating necks, and adjustable means for communicatively connecting the first flasks to the latter flasks.

10. A still comprising a pair of flasks having the neck of one bent and communicating with the intermediate portion of the neck of the other and a branch tube leading from the bent portion of the first neck, the necks being so disposed relative to each other as to permit pouring from either flask without pouring from the other.

In testimony whereof, I have hereunto subscribed my name this 21st day of July, 1919.

HENRY C. P. WEBER.
